Security of game cards such as instant lottery tickets can be improved by locating a confusion pattern below a primer layer on the game cards substrate and by locating another confusion pattern on a release coat above the game card play indica. Game card security can be further enhanced by using confusion pattern ink that bleeds through the game card in response to the application of various solvents.
L'inviolabilité des cartes de jeu du type billet de loterie instantanée peut être améliorée en plaçant une matrice de confusion sous la couche d'apprêt et en plaçant une autre matrice de confusion sur le masque des symboles cachés. L'inviolabilité desdites cartes peut être rehaussée davantage en utilisant une encre d'impression des matrices qui imprégnera la carte à coeur en réponse à toute tentative de dissolution par solvants.
